/** is used to execute SQL stored procedures.


	<p>
	SDBC provides a stored procedure SQL escape that allows stored procedures
	to be called in a standard way for all RDBMSs. This escape syntax has one
	form that includes a result parameter and one that does not. If used, the
	result parameter must be registered as an OUT parameter. The other parameters
	can be used for input, output, or both. Parameters are referred to sequentially,
	by number. The first parameter is 1.
	</p>
	<p>
	<code>{?=call&amp;lt;procedure-name&amp;gt;[&amp;lt;arg1&amp;gt;,&amp;lt;arg2&amp;gt;,...]}<br/>{call&amp;lt;procedure-name&amp;gt;[&amp;lt;arg1&amp;gt;,&amp;lt;arg2&amp;gt;,...]}
	</code>
	</p>
	<p>
	IN parameter values are set using the set methods inherited from
	<type scope="com::sun::star::sdbc">PreparedStatement</type>
	. The type of all
	OUT parameters must be registered prior to executing the stored procedure;
	their values are retrieved after execution via the
	<code>get</code>
	methods
	provided by the
	<type scope="com::sun::star::sdbc">XRow</type>
	.
	</p>
	<p>
	A
	<code>CallableStatement</code>
	can return one
	<type scope="com::sun::star::sdbc">XResultSet</type>
	or multiple
	<type scope="com::sun::star::sdbc">ResultSet</type>
	objects. Multiple
	<code>ResultSet</code>
	objects are
	handled using operations inherited from
	<type scope="com::sun::star::sdbc">XPreparedStatement</type>
	.
	</p>
	<p>
	For maximum portability, a call's
	<type scope="com::sun::star::sdbc">ResultSet</type>
	objects and
	update counts should be processed prior to getting the values of output
	parameters.
